SIGMUND V. HUBER, OF PITTSBURG, PENNSYLVANIA.

ROLLING-MILL TABLE.

SPECIFICATION forming part of Letters Patent No. 773,257, dated October25, 1904.

Application filed January 2, 1904. serial No. 187,528. (No model.)

To all whom it may concern:

Be it known that I, SIGMUND V. HUBER, a E bar or plate laterally fromthe table A' onto citizen of the United States, residing at Pitts burg,in the county of Allegheny and State of Pennsylvania, have invented ordiscovered certain new and useful Improvements in Rolling-Mill Tables,of which improvements the following is a specification.

The invention described herein relates to certain improvements in feedapparatus for rolling-mills, and has for its object a construction andcombination of parts'or elements whereby an article fed onto thereceiving-table of a rolling-mill can be transferred laterally onto astorage or cooling table, moved step by step across such table,transferred laterally to the feed-table of a shear or other mechanism.and fed longitudinally to such shear or other mechanism. The inventionis hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 isatop plan view of a portion of a feed apparatus embodying myimprovement. Fig. 2 is a sectional elevation of the same, the plane ofsection be ing indicated by the line II II, Fig. 1; and Fig. 3 is asectional elevation on a plane indicated by the line III III, Fig. 1.

In the practice of my invention the receiving-table, consisting of thepositively-driven feed-rollers 1 and supportingaprons 2, is arranged inthe line of feed of the rolls of a reducing-mill. This table is providedwith a suitable stop 3 to prevent the longitudinal movement of thearticlee. g. bars or platesoff the table. The aprons 2 are transverselyslotted, as at 4:, for the back-and-forth movement of a series ofshifting dogs 5, which are pivotally mounted on bars 6, arranged toreciprocate in suitable guideways 6. The dogs 5 are so constructed andarranged, as by weighting their rear ends, that the opposite ends willbe normally held projecting above the aprons, but will be free to beforced down by a bar or plate during the backward movement of the slides6. IVhile only one of, the slides 6, with its dog, is shown, it will beunderstood that in practice a number of such slides and dogs areemployed, the number being dependent on the length of the table A.

The slides 6, with their dogs, Will shift a the storage or cooling tableB, which is arranged alongside of the table A. The move ment of the barsor plates across table B is effected by a series of slides 7, mounted insuitable guides 8 and each provided With a series of dogs 9, similar inconstruction and operation to the dogs 5. The number of slides 7employed will depend upon the length of the table, and the number'ofdogs on each slide will be controlled by the Width of the table and thenumber of plates or bars to be stored thereon at one time. The range ofmovement of the slides 6 and 7 is such that the dogs on slides 6 willpush the bar or plate to such position that it can be caught by thefirst dogs of the series on the slides 7.

Provision is made to shift both series of.

slides 6 and 7 simultaneously and to impart a greater movement to theslides 6 than to the slides 7, for the reason that the dogs on slides 6must be capable of catching a plate or bar on any part of the table Aand shift it entirely off the table A, while it is only necessary thatthe dogs on slides 7 should advance the plate or bar at each stroke adistance a little greater than the width of the article.

The slides 6 and 7 are toothed on their under sides for engagement withtoothed wheels 10 and 11, secured, respectively, on shafts 12 and 13,extending longitudinally under the tables A and B. One of these shafts,as 12, rotates back and forth by any suitable means-as, for example, byfluid -pressure cylinders 14, having their common piston-rod 15 secu redto a rack-bar 16, which intermeshes with a toothed wheel 17 on the shaft12. By properly proportioning the stroke of the piston-rod and thediameters of the Wheels 17 and 10 the desired movement can be given tothe slides 6. It will be understood that the shaft 13 can be driven fromthe shaft 12 by the employment of a train of gearing; but as the shafts12 and 13 are located some distance 9 apart a number of gear-wheelsWouldbe required. In order to avoid such multiplicity of gear-wheels, arack-bar 18 is employed. This rack-bar is mountedJn suitable guideways19 and intermeshes with toothed wheels 20 and 21 on the shafts 12 and13, respectively. By properly proportioning the toothed wheels 20, 2.1,and 11 the desired movementof the slides T can be had from the shaft 12.

In order to shift the articles from table B to table G, which isprovided with positivelydriven feed-rollers 22, arranged transversely ofthe table, reciprocating slides 23 are employed. These slides areprovided with dogs 24, constructed and arranged in the same manner asthe dogs 5 and 9. The front ends of these dogs project normally throughtransverse slots 25 in the table 0, and the slides 23 are given such amovement that the dogs will engage an article in the position to whichit was shifted by the last of the series of dogs 9 and shift it to anydesired position on the table C. The slides 23 are provided with teethwhich inter-mesh with a pinion 26 on shaft 27. This shaft is rotatedback and forth by fluid-pressure cylinders 28, having a rack-bar 29connected to the common pis ton-rod and engaging a pinion 30 on theshaft 27.

1 claim herein as my invention- 1. An apparatus for rolling-mills havingin combination a receiving-table, reciprocating dogs for shifting thearticle across the receiving-table, a storage-table, two or more slides,each provided with a series of two or more dogs and mechanism forreciprocating the several dogs whereby an article is shifted from thereceiving to the storage table and moves step by step across the latter,substantially as set forth.

2. An apparatus for rolling-mills having in combination areceiving-table, reciprocating dogs for shifting the article across thereceiving-table, a storage-table, two or more slides movabletransversely of said table, each slide provided with a series of two ormore dogs, and means for simultaneously recipro' eating the dogs of thereceiving and storage tables different distances, substantially as setforth.

In testimony whereof I have hereunto set my hand.
